For serious backcountry skiers, snowboarders, or mountaineers, a reliable avalanche probe is essential safety gear. The Ortovox Alu 320+ PFA is a top choice. It's made from strong 7075 aluminum, extends to a full 320cm (about 10.5 feet) to search deep in debris, and uses a robust steel-cable tensioning system that won't stretch. The PFA assembly makes it compact to carry, and it has a quick-release strap. A large, replaceable tip helps it penetrate hard snow easily. It's a professional-grade tool built for speed, durability, and reliability in the worst conditions. Don't go into avalanche terrain without one.
